* Make channel layout masks unsignedMans Rullgard2011-11-25
| | | | | | | | | | It makes more sense for a bit mask to use an unsigned type. The change should be source and binary compatible on all supported systems, hence micro version bump. Fixes a few invalid shifts. Signed-off-by: Mans Rullgard <mans@mansr.com>
* dca: ARMv6 optimised decode_blockcode()Mans Rullgard2011-11-25
| | | | | | | | | This is a hand-tuned version of the code with impossible parts of the FASTDIV function ommitted. 2-5% faster overall on Cortex-A8. Signed-off-by: Mans Rullgard <mans@mansr.com>
* frame-mt: return consumed packet size in ff_thread_decode_frameJanne Grunau2011-11-25
| | | | | This is required to fulfill avcodec_decode_video2() promise to return the number of consumed bytes on success.
* snow: split snow in snowdec and snowencLuca Barbato2011-11-24
| | | | | The common non inlined code goes in snow.c, the common inlined code in snow.h, tables move in snowdata.h (included only by snow.c)
* tiffenc: deprecate using compression_levelAnton Khirnov2011-11-24

* pcmdec: remove unneeded resetting of samples pointerJustin Ruggles2011-11-23

* bethsoftvideo: return proper consumed size for palette packets.Anton Khirnov2011-11-23
| | | | Also check for sufficient packet size.
* tiffenc: add a private option for selecting compression algorithmAnton Khirnov2011-11-23

* ARM: remove needless .text/.align directivesMans Rullgard2011-11-23
| | | | | | | The 'function' macro already includes the appropriate directives. Signed-off-by: Mans Rullgard <mans@mansr.com>
* aacdec: Fix PS in ADTS.Alex Converse2011-11-22
| | | | Fixes File1.aac and Bug 80.
* dsputil: use cpuflags in x86 emu_edge_coreJustin Ruggles2011-11-22
| | | | avoids passing around the extra argument among all the macros it uses
* dsputil: use movups instead of movdqu in ff_emu_edge_core_sse()Justin Ruggles2011-11-22
| | | | | This allows emulated_edge_mc_sse() and gmc_sse() to be used under AV_CPU_FLAG_SSE.
* wma: initialize prev_block_len_bits, next_block_len_bits, and block_len_bits.Justin Ruggles2011-11-22
| | | | | | | | The initial values are not checked against the number of block sizes. Initializing them to frame_len_bits will result in a block size index of 0 in these cases instead of something that might be out-of-range. Fixes Bug 81.
* Add libavutil/mathematics.h #includes for INFINITYMans Rullgard2011-11-22
| | | | | | This fixes build errors in some environments. Signed-off-by: Mans Rullgard <mans@mansr.com>
* doxy: introduce an empty structure in libavcodecLuca Barbato2011-11-22
|
* ARM: add explicit .arch and .fpu directives to asm.SMans Rullgard2011-11-22
| | | | | | | | | | | | | This prevents build errors when compiler and assembler default targets differ. Ideally each file would declare the highest level it requires. This is however not easily possible as it complicates assembling pre-armv6t2 code in Thumb-2 mode. HAVE_NEON is used as indicator for ARMv7-A since no other symbol exists for this and NEON is only available in this variant. Signed-off-by: Mans Rullgard <mans@mansr.com>
* pthread: do not touch has_b_framesJanne Grunau2011-11-22
| | | | | | | | | | | | | | | | | | Adding the thread count in frame level multithreading to has_b_frames as an additional delay causes more problems than it solves. For example inconsistent behaviour during timestamp calculation in libavformat. Thread count and frame level multithreading are both set by the user. If the additional delay caused by frame level multithreading needs to be considered in the calling code it has all information to take it into account. Should it become necessary to calculate a maximum delay inside libavcodec it should be exported as its own field and not reusing an existing field. Based on a patch by Michael Niedermayer.

* avcodec: move some AVCodecContext fields to an internal struct.Justin Ruggles2011-11-19
| | | | | | | | A new field, AVCodecContext.internal is used to hold a new struct AVCodecInternal, which has private fields that are not codec-specific and are used by general libavcodec functions. Moved internal_buffer, internal_buffer_count, and is_copy.

* vble: remove vble_error_closeJanne Grunau2011-11-11
| | | | | | It does not make much sense to factor the error handling to its own av_always_inline function. Fixes "format not a string literal and no format arguments" warning in the av_log.
